3 Claims. (Cl. 40-107) The present invention relates to a desk calendar, and has for an object to provide a device of this character wherein a perpetual monthly calendar element is adjustably arranged in a sight opening so that the particular starting day of each month may be disposed in proper relation to a fixed element indicating the days of the week in their usual arrangement from Sunday to Saturday, and further to provide a changeable month indicating element for the months of a particular year including a designation of the first day of each month and the number of days therein, whereby the monthly calendar element may be adjusted in the sight opening to show any month of the year.

A further object is to provide a calendar device which may be conveniently operated to bring any desired month of the year into place in a sight opening, and to bring the monthly calendar into relation in a sight opening to show the particular month, so that, if it is desired to determine the particular day of the week upon which any past or future date may fall, this can be quickly and accurately accomplished.

Another object is to provide a calendar device of permanent form and usability as a desk accessory. To this end, it is proposed to provide the month indicating means in the form of a renewable band removably attached to the device, in combination with a renewal strip containing month indicating bands for a number of years, as for instance, l years, and further to provide container means for such renewal strip, so that the latter may be furnished as a part of the cal-V endar device and will not become lost or mutilated through separation from the device.

Another object is to provide a month-indicating member giving the starting day indications for a particular year, and which may be conveniently and economically replaced each year.

t A further object is to provide an indicating means in combination with the calendar device whereby the current day, or some particular day that the user desires to be reminded of, may be visually indicatedso as to emphatically distinguish it from the other days of the month.

With the above and other objects in view, an embodiment of the invention is shown in the accompanying drawing and this embodiment will be hereinafter more fully described with reference thereto, and the invention will finally be pointed out in the claims.

In the drawing- Fig. 1 is a perspective view of 'a desk calendar device according to one illustrated exemplary embodiment of the invention.

Fig. 7a is a. fragmentary vertical sectional view ofthe casing element of the device, showing a modified form of indicating band member associated therewith.

Similar reference characters indicate corresponding parts throughout the several figures of the drawing.

Referring to the drawing, the desk calendar device, according to the illustrated exemplary embodiment of the invention shown therein, comprises a casing member I0 of hollow open-ended sleeve form and of triangular cross-section rounded at the longitudinal corners, the bottom portion thereof being horizontally disposed and secured to a base stand I I, and the front wall face portion being preferably wider than the back Wall portion, yso that it is disposed at a relatively lower angle than the back wall portion and is therefore more conveniently disposed for viewing the calendar. 'Ihe base stand II is provided centrally with a transverse clearance slot I2 somewhat longer than the monthly calendar lviewing opening of the casing, for receiving an adjustable indicating band element, hereinafter more fully referred to.

Substantially centrally of the face ofthe casing III there is provided a rectangular monthly calendar sight opening I3 .ab'ove'whichthere is provided a legend I4, corresponding to the length of the opening, and divided into seven equal spaces respectively indicating the days of the week from Sunday to Saturday. Above this legend Il!v there is provided an elongated sight opening I5 in which is displayed the month indicating element as will presently more fully appear. At each end of the casing at the upper corner portions formed by the front and back wall portions there are provided cut-out recesses ,I6- I6 in which are disposed the knob ends of the month indicating element, as Willpresently more fully appear. 1"

The adjustable monthly calendar element is in the form of a block member I'I, slidably fitted within the casing member III to engage its bottom, face and back wall portions, and substantially less in length than the casing to permit of limited sliding adjustment movement therein. In the upper side of the block member there is provided a semi-cylindrical cradle bearing recess I8, of such radius that a cylinder of corresponding radius will contact the inner surfaces of the front and back walls of the casing member, with these surfaces tangential to the cylinder, this being for the purpose for providing Ya bearing for the cylindrical month indicating element presently to be more fully described.

Upon the face side of the block member I'I there is provided a rectangular depression I9 in which is secured by pasting, or other suitable means, a calendar sheet 2U, a portion of which shows through the sight opening I3 of the casing, the depression being slightly deeper than the thickness of this calendar sheet so that its surface will be out of rubbing contact with the casing and will therefore not become worn through the sliding adjustment movement of the block member. The calendar sheet contains a series of calendar numbers arranged in blocks, there being thirteen rows of blocks lengthwise of the sheet and six rows of blocks crosswise,

and these blocks being so dimensioned that seven of the lengthwise rows correspond in length to the length of the sight opening I3. In the top row of blocks starting with the seventh block from the left there are provided the daily date indications 1 to 7, in the second row of blocks there are provided the indications 2 to 14, in the third row the indications 9 to 21, in the fourth row the indications 16 to 28, in the fifth Vrow the indications 23 to 31, and in the sixth row in the indications 30 and 31. This arrangement is such that by longitudinally adjusting the block member the rst day of the month may be disposed at any one of the seven days indicated by the legend I4 and all of the daysof the month will be shown in the sight opening in their proper order.

In order to block out the date indications 29, 30 and 31, in the case of months respectively having 28, 29 and 30 days, a longitudinally slidable shield element 2l is provided, its end portions being slidably engaged in longitudinally disposed recesses 22-22 at each end of the face of the block member, this shield member having a step-shape upper edge, whereby longitudithe fth row containing the. date number 23 to 31, and with the sixth row containing the numbers 30 and 31, the length of this shielding portion being such that it can be moved intoV concealing position to any or all of the date indications of the fifth and sixth rows. Thus in the case of February having 28 days and starting on Sunday the i'lfth and sixth rows will be concealed, while in the case of a 3l-day month startof the casing member, this cylinder member being engaged in the cradle bearing recess I8 of the block member I'I and having bearing contact at its upper side with the front and back Walls of the casing member, the length of the cylinder member corresponding to the distance between the cut-out portions I6 at the end of the casing member, so that the knobs are disposed within these cut-outs with their shoulder abutment inner surfaces engaging the end surfaces of the cut-outs, so as to X the cylinder against longitudinal displacement, while permitting it to be rotated through turning the knob ends. The projection of the knob ends also provides stop means for limiting the longitudinal sliding movement of the block member I1, preventing its disengagement from the casing member:V

The intermediate portion 25 of the cylinder `member is slightly depressed with respect to the of the months from January to December, with designations of the particular year, the starting day of each month, and the number cf days in each month for the particular year for which the sheet is provided. For instance, the month as shown in Figs. 1 and 2 is January, 1943, and shows the starting day as Friday and the number of days as 31, so that the monthly calendar is adjusted to show the first of the month as Friday, and the shield 2I is adjusted to expose the 31st day. It will be obvious that if it is desired to determine any particular day of the year, past or future, the cylinder may be turned to bring vthe desired month into view with its starting day indication, the block I1. being then longitudinally adjusted to bring the indicated starting day Ainto place,

The cylinder 23 is preferably hollow and provides a convenient receptacle for containing a renewal strip 21 containing month indications, and which may be furnished in suicient length to provide the month indications of a number of years, so that at the start of a new year the portion of the strip 21 for that particular year may be cut from the strip and placed upon the cylinder. If desired the complete cylinder member may be replaced each year by a new member having the current year month indication thereon, thus making of the device an effectual long range advertising medium which may be brought nal shielding portions are provided in line with j 11D t0 date eaCh yea? by the advertiser furnishing a replacement cylinder member.

In order to indicate the current day, or provide a reminder for any particular day, a transparent band member 28 is engaged about the casing through the slot I2, being formed of suitable pliable material whereby it can be moved around the casing to any desired position by sliding over the rounded corners thereof. At one point of this band there is provided a distinctively colored transparent block portion 29 corresponding in dimension to one of the blocks of the monthly calendar, so that it can be placed in register with any particular block desired, the band in addition to its movement around the casing being also adapted to be slidably moved thereon longitudinally. The slot I2 is preferably sufliciently longer than the sightopening I3 so that the band may be moved beyond either end of the sight opening when it is not in use to indicate a particular day.

In Fig. '7a the band member 28 is shown in a modified arrangement, being disposed horizontally about the front wall of the casing, and extending around its end edges, In addition to indicating a particular day, this band indicates the particular week and for this purpose may be lightly colored to contrast with the calendar sheet.

I have illustrated and described a preferred and satisfactory embodiment of the invention, but it will be understood that changes may be made therein, within the spirit and scope thereof, as dened in the appended claims.
